Take the Pro X Series Fat Sac™ and add 38 inches to its length... that’s right, this thing is massive. The Center Gravity Games Ballast Sac is only one inch smaller in width and height but at over 3 feet longer, it weighs in at nearly twice the weight of a single Fat Sac™. Try combining this sac with two Rear Gravity Games Sacs for one monster of a wake.

This sac does not come with the fittings to work automatically with the Tsunami Pump.
